Subject: [dpdk-dev] [PATCH v8 1/3] ethdev: add level support for RSS offload types
Date: Thu, 17 Sep 2020 07:37:33 +0530
Message-ID: <20200917020735.2195069-1-kirankumark@marvell.com> (raw)
In-Reply-To: <20200901032708.58247-1-kirankumark@marvell.com>

From: Kiran Kumar K <kirankumark@marvell.com>

This patch reserves 2 bits as input selection to select Inner and
outer encapsulation level for RSS computation. It is combined with existing
ETH_RSS_* to choose Inner or outer layers.
This functionality already exists in rte_flow through level parameter in
RSS action configuration rte_flow_action_rss.

Signed-off-by: Kiran Kumar K <kirankumark@marvell.com>

V8 Changes:
* Re-worked the level parameters. Added as PMD_DEFAULT, LEVEL_OUTERMOST,
LEVEL_INNERMOST
